The Lowdown
Alright, Rusty here. Let’s talk about Kennebunk Beach.
Honestly, it’s a tough stretch ahead. For the next two weeks, there's nothing that really gets the blood pumping. We’re looking at a lot of small, weak surf, and the wind is often messy. There are a few days where the waves have a little bit of size, but it’s never all coming together.
The water temperature is sitting at 63°, which is a touch warmer than normal for this time of year, so at least you won’t be freezing your toes off.
The first real window of opportunity doesn’t show up until the 24th of September. Thursday morning a new swell pushes in, about 5ft from the SE with moderate energy (165). It’s clean with a light offshore wind, but the vibe is "surfable but very ordinary." It’s not going to blow your mind, but it’s something to get a wet suit on for. The afternoon goes a bit choppy.
After that, we drop back into small stuff again, but the real standout is late in the month. On the 30th of September, Wednesday, we finally get a proper pulse. Wednesday morning brings 7ft of swell from the east with strong energy (525), light cross-off winds, and that’s clean. Wednesday afternoon is even better: 8ft from the ESE, very strong energy (826), and offshore wind. That’s a solid groundswell, and with the period at 8-9 seconds, it’s got some punch. The sets will be a bit walled up for the beach break, but if you can find a sandbar working, it’ll be the best day on offer in the whole window. That size is really only for experienced surfers, though; beginners should stay well clear.
So for now, it’s a waiting game. The end of the month is the only real highlight, and it’s still a couple of weeks out, so keep an eye on it. Forecasts can change.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
